Twice in the past week, activists have posted information on employees of U.S. Immigration and Customs Enforcement (ICE), the agency that carried out Trump’s policy that required children to be separated from their parents who were arrested for crossing the U.S. border illegally. Amid national bipartisan outrage, Trump abruptly reversed course last week.

Sam Lavigne, an adjunct professor at New York University, last Tuesday posted data on 1,595 ICE employees that he scraped off of profiles on LinkedIn, a career networking platform. Lavigne posted the material on GitHub, a hosting platform popular with software developers.

“I leave it here with the hope that researchers, journalists and activists will find it useful,” Lavigne wrote in a blog posting on Medium that has since been taken down.

WikiLeaks, the radical transparency group that has published millions of documents over the past decade, on Friday posted what it called ICE Patrol, a website with biographical information on 9,243 people it said were employees of ICE or linked to the agency.

ICEPatrol is an important public resource for understanding ICE programs and increasing accountability, especially in light of the actions taken by ICE lately, such as the separation of children and parents at the US border.

“This assessment is based on specific and credible threats that have been levied against certain DHS employees and a sharp increase in the overall number of general threats against DHS employees,” the email read, adding that “over the last few days, thousands of employees have had their personally identifiable information publically released on social media.”
